my iTouch is weird

A few days ago (more specifically Friday of last week), my iTouch  slipped to the floor when I had many books in my hand. At the time, I naively thought my iTouch would be alright. After all, my cell phone had suffered more serious injuries and it seemed to be fine. I have thought wrong. it first, it was just stuck. It was just a black screen. Then, I tried to restart the thing. This only resulted in a white screen. Later that day however, I thought it has fully recovered when I tries to restart the iTouch and it went back to normal. But now, my iTouch is getting really weird. Sometimes, it would just give me a blank white screen. I have to tap it several times until i gets back to normal. Sigh... I've only gotten it for two months and now its already broken.
